What is Fluorine
Fluorine (from L. fluere, meaning "to flow"), is the chemical element in the periodic table that has the symbol F and atomic number 9. Atomic fluorine is univalent and is the most chemically reactive and electronegative of all the elements. In its pure form, it is a poisonous, pale, yellow-green gas, with chemical formula F2. Like other halogens, molecular fluorine is highly dangerous; it causes severe chemical burns on contact with skin
.
Fluorine's relatively large electronegativity and small atomic radius makes it have some interesting bonding characteristics.
Pure fluorine (F2, since fluorine is diatomic) is a corrosive pale yellow gas that is a powerful oxidizing agent. It is the most reactive and electronegative of all the elements, and readily forms compounds with most other elements. Fluorine even combines with the noble gases, krypton, xenon, and radon. Even in dark, cool conditions, fluorine reacts explosively with hydrogen. It is so reactive that glass, metals, and even water, as well as other substances, burn with a bright flame in a jet of fluorine gas. It is far too reactive to be found in elemental form and has such an affinity for most elements, including silicon, that it can neither be prepared nor be kept in glass vessels. In moist air it reacts with water to form the equally dangerous hydrofluoric acid .
In aqueous solution, fluorine commonly occurs as the fluoride ion F-. Other forms are fluoro-complexes, such as [FeF4]-, or H2F+.
Fluorides are compounds that combine fluorine with some positively charged counterpart. They often consist of ions. Fluorine compounds with metals are among the most stable of salts. |
